Abstract

High-need patients, the 5% of persons who account for 50% of health care spending (Mitchell, 2016), require post-acute care designed to address their unique combination of behavioral, social, functional, and clinical complexities. The American Hospital Association defines high-need, high-cost (HNHC) patients “... as adults who have three or more chronic diseases and functional limitations in their ability to care for themselves or perform routine daily tasks” (American Hospital Association, 2017). Indeed, taxonomy defines six segments of the high-need population based on its clinical/functional and social/behavioral characteristics (Long et al., 2017). The segments range from children with complex needs to adults with advancing illness; however, this review focuses on transitional care management (TCM) for adults in four of the six segments: those with multiple chronic or major complex chronic conditions and those with functional limitations, including frail elderly and nonelderly persons with disability. Recently, value-based care management models have been designed to reduce unnecessary hospital utilization during transitions from the hospital (both inpatient and emergency departments) to posthospital care in facilities and the community by addressing the complex needs of these segments (Kripalani, Theobald, Anctil, & Vasilevskis, 2014). Critical components of these programs include segmentation of high-need patients to match services with needs, team-based care, health information exchange (HIE), and payment for nonmedical treatment (Blumenthal & Abrams, 2016).

The models in the United States range from post-acute programs that attempt to reduce length of stay and prevent readmissions (Burke et al., 2015; Cross & Adler-Milstein, 2016) to complex case management embedded in primary care settings (Hochman & Asch, 2017) that often include integrated behavioral health services (Desmedt et al., 2016). However, the care management activities are often setting-specific and result in poor continuity of care even when decreasing hospital (low-value) utilization. Questions about how programs hand off responsibility to the next care providers remain, and the decisions are often influenced by eligibility criteria (Bowles et al., 2019; Buntin, Colla, & Escarce, 2009). Providers question the necessity of using professional staff to provide transitional care services. The purpose of this scoping review is to focus on the integration and coordination of services for HNHC patients as they transition between the acute, post-acute, and outpatient settings.

Background

Transitional Care for High-Need Cases

Two seminal transitional care programs highlight the controversy about appropriate staffing for transitional care. The transitional care model as it has evolved uses advanced practice registered nurses (APRNs) to provide patient-centered, comprehensive holistic care and to provide oversight to other team members (Hirschman, Shaid, McCauley, Pauly, & Naylor, 2015; Naylor et al., 2018). The model includes seven components, including engaging elderly persons and their caregivers in care planning, assessing symptoms and risks, preparation for self-management, collaboration and communication with team members, and coordination of services (Naylor et al., 2018). In contrast, in the care transitions intervention, a transitions coach trained in a 4-week program develops a close relationship with the patient and the caregiver and coaches the older adult in self-management. The model focuses on medication self-management, dynamic care plan shared across settings, patient/family support for physician follow-up, and knowledge of red flags specific to the medical condition (Coleman, n.d.). Both models are considered best practice (Rochester-Eyeguokan, Pincus, Patel, & Reitz, 2016) because they included a multimodal intervention, a multidisciplinary team, bridged across settings, were tested in multiple settings or for multiple conditions, and reported positive patient outcomes. Only two other models met Rochester-Eyeguokan et al.'s criteria for best practice: Project RED (reengineered discharge) (Jack et al., 2009) and Project BOOST (Hansen et al., 2013). In all of these programs, the concepts of bridging care across the acute and post-acute settings and using a care plan to coordinate care among team members were essential to success in reducing readmissions (Burke, Kripalani, Vasilevskis, & Schnipper, 2013).

Complex care management targets continuity of care and aims to replace low-value inpatient and emergency utilization with coordinated care outside the hospital setting (Blumenthal & Abrams, 2016; Hong, Siegel, & Ferris, 2014). Successful complex care management promotes value-based care, segments the high-need population into cohorts with similar needs, aligns the care team to the specific needs, and exchanges electronic health information (Blumenthal & Abrams, 2016). In addition, continuity requires consideration of the relationship between the patient and providers as well as connections between providers (Hong et al., 2014). Because of the focus on avoiding readmissions, transitional care tends to concentrate on improving the hospital discharge to post-acute care whereas complex care management focuses on stabilizing the person in the community. Increasingly, technology is playing an important role in complex care management through HIE (Cross & Adler-Milstein, 2016; Hewner, Sullivan, & Yu, 2018) and in development of algorithms to identify cases requiring post-acute services (Keim & Bowles, 2018). These data-driven approaches have the potential to improve continuity between the hospital and post-acute settings.

Integrated care programs provide comprehensive, team-based care for specific segments of the high-need population, especially those with comorbid behavioral conditions and chronic disease (Rosenberg et al., 2014). Integrated care focuses on the continuum of preventive and restorative services needed by those with multiple chronic conditions delivered by a range of health professionals with coordination of these services across the continuum (Desmedt et al., 2016). Collaborative care management includes systematic psychiatric assessment, nonphysician symptom monitoring, specialist recommendations, and care coordination (Huffman, Niazi, Rundell, Sharpe, & Katon, 2014). The TEAMcare trial treated patients with depression that complicated the management of poorly controlled diabetes within the primary care setting and improved adherence to diet and exercise recommendations (Rosenberg et al., 2014). Depressed patients had faster remission and shorter duration of persistent depressive symptoms in collaborative care that included a registered nurse (RN) care manager and an integrated behavioral health team (Garrison, Angstman, O'Connor, Williams, & Lineberry, 2016). Although these programs did not evaluate the impact on low-value utilization, colocating behavioral health providers within the primary care setting improved continuity for high-need patients.

Patient-centered medical homes are becoming increasingly involved in developing care management models for high-need patients because of the emphasis on value-based payment (Hewner et al., 2017; Hochman & Asch, 2017). The practice-based approach embeds complex case management within the primary care setting. However, the need to have multidisciplinary resources to coordinate services for high-need patients can be burdensome for office-based practices. In contrast, the centralized approach to care management for high-need, high-cost patients uses an RN or social worker to lead a multidisciplinary team but is located outside of the practice (Holtrop, Potworowski, Fitzpatrick, Kowalk, & Green, 2016; Luo et al., 2016). Finally, a number of primary care practices are experimenting with embedding community outreach workers in primary care to address social determinants of health (Freund et al., 2016; Goldman, 2018). Embedded complex care management may have additional benefits because of the opportunity for face-to-face interaction between team members (interactional workability), enhanced skill sets, organizational support (contextual integration), and long-term relationship with the patient (relational integration) that result in improved continuity for the patient (Holtrop et al., 2016).

The research questions that guided this review are as follows: “What models of transitional care are being used to manage HNHC patients in the United States?” and “How effective are they in reducing low-value utilization and in improving continuity?” We hypothesized there was an evolution from models that focused solely on transitions to reduce readmissions to ones that used care management strategies to keep people with complex chronic conditions, social needs, and functional decline out of the hospital.

Methods

Protocol

The methodology for this scoping review was based on the Joanna Briggs Institute (JBI) Reviewers' Manual 2017 Methodology for JBI Scoping Reviews (Peters et al., 2017). In keeping with the JBI methodology, the reviewers developed a protocol to define objectives, methods, and inclusion/exclusion criteria prior to study selection and data extraction.

Information Sources

A methodical search was conducted in December 2018 in PubMed, CINAHL, Web of Science, and EMBASE databases using key words and medical subject headings (MeSH) listed in Table 1. The categories of concepts were models of transitional care, HNHC patients and outcomes (utilization and continuity).

TABLE 1 - Key Words and Medical Subject Headings (MeSH)
Category 1 (Care Management Models) Category 2 (High-Need, High-Cost) Category 3 (Outcomes)
Care management Disabled Emergency department visits
Integrated care Multiple chronic illness Hospital admissions
Transitions of care Frail elderly Continuity
Transitional care model Advancing illness
Care transitions Chronic illness
Care coordination Super utilizer
Post-acute care High-need, high-cost
Managed long-term care Multimorbidity
Aging in place

Search Strategy

A stepwise method to search the databases was used by exploring and combining three concepts from the MeSH key words with assistance of a Health Sciences librarian who had expertise in systematic review searching. An example of full Web of Science search strategy is provided in Table 2. This search strategy was adapted to the syntax and consistently applied to the rest of the database.

Eligibility Criteria

Qualitative, quantitative, and mixed-methods research articles were searched and selected using specific inclusion and exclusion criteria (see Table 3). To keep the scope of the review as broad as possible, the reviewers did not restrict study inclusion to a particular research methodology, intervention, or target population with the exception of excluding patients younger than 18 years. Because of the influence of government-based payer systems and policies on models of care, studies were restricted to those conducted in the United States within the past 10 years.

Literature Search Results

The search strategy yielded an initial 1,088 references (see Figure 1), and no additional new references were identified from other web-based sources or manual searching. Duplicate references (n = 68) were discarded from across the four bibliographic sources (CINAHL, EMBASE, PubMed, and Web of Science). Based on title and abstract review for eligibility criteria of original research articles, studies with an adult focus and articles incorporating transitional care model in the United States, 121 abstracts were then retrieved and read. Of these, 995 references were removed and 25 were extracted for full-text review. Six articles were excluded at this stage because they did not meet the original inclusion criteria, which were identified when reading the full text in detail. The excluded studies related to long-term care (Hicks & Cimarolli, 2018; Temkin-Greener, Bajorska, & Mukamel, 2008; Weaver et al., 2008), narrowly defined populations (Bandy et al., 2014), had the wrong outcome (Berg, Donnelly, Miller, Medina, & Warnick, 2012), or focused on electronic health record (EHR) integration (Graetz et al., 2014). Thus, 19 references were selected for this scoping review following critique of the full-text articles.

Study Selection

Results of the database search were imported into the Covidence systematic review management system (Covidence, n.d.). Duplicates were removed, and two reviewers independently screened the titles and abstracts of the remaining studies while a third reviewer screened discrepancies. Two reviewers then reviewed the remaining potentially relevant articles in full text, with disagreements again resolved by a third reviewer or by group consensus. The team of reviewers met routinely through videoconferencing throughout the scoping review process. Consistent with the JBI scoping review methodology, the inclusion and exclusion criteria were refined in an iterative fashion as the reviewers became more familiar with the available evidence.

Data Extraction

A preliminary data collection tool was developed in Excel, and fields were agreed upon by all reviewers prior to data extraction. Each article was read in full, and data were extracted and charted by one author and reviewed/confirmed by a second author. Extracted fields included study design, sample, population, model, interventions, utilization outcomes, and continuity outcomes.

Quality Appraisal and Risk of Bias

The quality of each study was assessed using the applicable JBI Critical Appraisal Tool for each (i.e., randomized control trial [RCT], cohort study, quasi-experimental, and case series/report). Studies ranged from fair to very high in quality and impact. No study was determined to have poor quality. Because of the specificity of the review criteria and paucity of research on the HNHC population, all eligible studies were included regardless of quality rating.

Results

Study Characteristics

The initial search strategy returned 1,088 studies for screening. After removal of duplicates and application of inclusion and exclusion criteria, 19 studies were selected for this review. The heterogeneity of the methods, target populations, care models, interventions, and outcomes made study comparisons challenging. Of the 19 articles, four were RCTs (Boult et al., 2011; Brown, Peikes, Peterson, Schore, & Razafindrakoto, 2012; Hanrahan, Solomon, & Hurford, 2014; Zulman et al., 2017) and three were case studies (Fleming & Haney, 2013; Kitzman, Hudson, Sylvia, Feltner, & Lovins, 2017; Waxmonsky et al., 2011). Table 4 highlights the design, sample size, and outcomes of the studies. The remaining articles were a mix of observational, quasi-experimental, cohort, and descriptive studies. Sample sizes ranged from 18 (Hanrahan et al., 2014) to 22,000 in an 11-site study (Brown et al., 2012), for a total of 35,939 participants over all studies. One study was conducted in a rural setting (Kitzman et al., 2017), five studies used multiple sites or the setting was not specified (Baldwin, Zook, & Sanford, 2018; Brown et al., 2012; Fleming & Haney, 2013; Kim, Higgins, Esposito, & Hamblin, 2017; Waxmonsky et al., 2011), and the remaining studies were conducted in urban or suburban areas.

Outcomes

The most frequently measured outcomes concerned health services utilization. Conversely, very few measured continuity of care. All 19 studies measured hospital admissions or readmissions as the primary outcome. Fifteen of the 19 studies looked at emergency department utilization (Block et al., 2013; Boult et al., 2011; Chen et al., 2015; Chu et al., 2017; Graham, Liu, Hollister, Kaye, & Harrington, 2018; Hanrahan et al., 2014; Hardin, Kilian, Muller, Callison, & Olgren, 2017; Kim et al., 2017; Kitzman et al., 2017; Sander et al., 2018; Steele, Ungemack, Mormile-Mehler, & Rabitaille, 2017; Watkins, Hall, & Kring, 2012; Waxmonsky et al., 2011; Zulman et al., 2014,2017). Additional service utilization measures included hospital days (Boult et al., 2011; Hardin et al., 2017; Ohar, Loh, Lenoir, Wells, & Peters, 2018; Steele et al., 2017), primary or specialty care visits (Boult et al., 2011; Graham et al., 2018; Ohar et al., 2018; Steele et al., 2017; Waxmonsky et al., 2011; Zulman et al., 2017), home health visits (Boult et al., 2011; Watkins et al., 2012), and skilled nursing utilization (Boult et al., 2011). Nine studies measured financial outcomes including costs or savings (Baldwin et al., 2018; Brown et al., 2012; Hardin et al., 2017; Sander et al., 2018; Steele et al., 2017; Watkins et al., 2012; Waxmonsky et al., 2011; Zulman et al., 2014,2017). Other outcome measures included patient satisfaction (Graham et al., 2018; Sander et al., 2018; Watkins et al., 2012; Zulman et al., 2017), health-related quality of life (Hanrahan et al., 2014; Watkins et al., 2012), care continuity (Hanrahan et al., 2014), and mortality (Chen et al., 2015; Ohar et al., 2018).

Target Population

The studies varied in target populations. Some studies incorporated specific payer groups into their study inclusion criteria including four studies that focused on Medicaid patients (Chu et al., 2017; Kim et al., 2017; Sander et al., 2018; Waxmonsky et al., 2011), one on Medicare patients (Brown et al., 2012), one on dual-eligible patients (Graham et al., 2018), two on veterans (Zulman et al., 2014,2017), and one on the uninsured or underinsured (Block et al., 2013). The remaining studies included multiple payer groups or did not address payer group. In addition, one study's inclusion criteria included specific medical conditions including three on behavioral health (Hanrahan et al., 2014; Kim et al., 2017; Steele et al., 2017) and one study each on stroke (Kitzman et al., 2017) and chronic obstructive pulmonary disease (Ohar et al., 2018).

The remaining 10 studies targeted populations deemed HNHC; however, there were inconsistent criteria for defining HNHC patients across studies. Patients deemed HNHC included people with disabilities (Chu et al., 2017), chronic medical conditions (Brown et al., 2012), requiring specialty care (Block et al., 2013), and requiring home health (Fleming & Haney, 2013). Two studies defined HNHC based on the patient's prior health care utilization patterns including inpatient and emergency department visits (Hardin et al., 2017; Sander et al., 2018). Three studies defined HNHC as a combination of chronic medical conditions and prior health care utilization (Brown et al., 2012; Watkins et al., 2012; Zulman et al., 2014). Three studies used specific tools to define patients as HNHC. Boult et al. (2011) used the claims-based hierarchical condition category predictive model (Pope et al., 2004) to estimate a patient's health expenditure risk. Chen et al. (2015) used the Elder Risk Assessment score (Takahashi, Chandra, Cha, & Borrud, 2011; Centers for Medicare & Medicaid Services, 2014), and the 4-year prognostic index score identified homebound frail patients with life-limiting illness (Lee, Lindquist, Segal, & Covinsky, 2006). The VA Care Assessment Need risk prediction algorithm (Wang et al., 2013) was used by Zulman et al. (2017) to identify patients at high risk of hospitalization. Finally, Waxmonsky et al. (2011) defined HNHC as those patients in the top 20% highest cost in the prior year or highest risk by case-mix index or Kronick score (Kronick, Gilmer, Dreyfus, & Lee, 2000).

Care Management Models

The synthesis clustered 18 studies into four categories of care management (excluding the Brown et al. meta-synthesis of demonstration projects): integrated behavioral health and primary care; embedded interprofessional care management teams; centralized care management; and TCM models. Three studies (Kim et al., 2017; Sander et al., 2018; Steele et al., 2017) employed integrated and colocated teams that included both behavioral health and primary care providers. Care management teams included non-nurse navigators (Block et al., 2013; Watkins et al., 2012) and nurses in the role of care coordinator (Boult et al., 2011; Chu et al., 2017; Zulman et al., 2014,2017). Centralized care management models provided care management remotely (Chen et al., 2015; Graham et al., 2018; Hanrahan et al., 2014; Hardin et al., 2017; Waxmonsky et al., 2011), and the remaining studies focused on transitional care from the hospital to another setting (Baldwin et al., 2018; Fleming & Haney, 2013; Hanrahan et al., 2014; Kitzman et al., 2017; Ohar et al., 2018). However, many studies combined characteristics of multiple models (Boult et al., 2011; Hanrahan et al., 2014; Kim et al., 2017; Watkins et al., 2012; Waxmonsky et al., 2011).

Intervention Characteristics

Regardless of the model employed, studies delivered complex interventions that used multiple components as described in Table 5. The majority of studies used an identified individual (APRN, RN, social worker, or navigator) to guide the transition intervention, usually in combination with multidisciplinary team-based care. Other components of the transitional care interventions were service based and included comprehensive assessment of discharge needs, comprehensive education about disease self-management and behavior change, behavioral mental health interventions, increased number of contacts, medication review/management, increased access to community resources, and quality outcome tracking.

Impact of the Studies

The 19 studies ranged in impact from fair (2) to very high (5) on a 5-point scale that considered the quality of study design, the complexity of the target population, the intensity of the intervention, and the significance of the results. Table 6 displays the studies and their care management model, ranked according to impact. It is important to note that all studies reported outcomes for a regional rather than national impact, and this limits the ability to generalize the results. Studies with the highest impact (Boult et al., 2011; Brown et al., 2012; Zulman et al., 2017) used multidisciplinary team-based care, with an RN or APRN as communication hub, and included comprehensive assessment of discharge needs and comprehensive education about self-management and behavior change, among other high-intensity interventions. The highest impact studies based their target populations on both chronic disease history and risk for utilization for Medicare and veteran patients.

Note. CM = care management; ED = emergency department; PCMH = patient-centered medical home; RCT = randomized controlled trial.

One RCT examining patients discharged from inpatient psychiatric care (Hanrahan et al., 2014) was rated as very good because the outcomes were not statistically significant. The other integrated behavioral health models were rated very good (Kim et al., 2017) or good (Sander et al., 2018; Steele et al., 2017) based on if there was a control population. Interventions varied in models targeting behavioral health populations; however, all but Kim et al. (2017) included APRNs or social workers or both as part of the team.

Three other observational studies with control groups and positive outcomes were rated as very good (Hardin et al., 2017; Ohar et al., 2018; Waxmonsky et al., 2011). Although the studies targeted different populations, a common feature of the studies was the inclusion of a care plan or care map (Hardin et al., 2017). Three transitional care models were rated as having a fair impact because they were case studies without controls, but they reported positive outcomes (Baldwin et al., 2018; Fleming & Haney, 2013; Kitzman et al., 2017). Zulman et al. (2014) also rated their study as fair, but it was a preliminary study to Zulman et al. (2017).

Discussion

Similar to past reviews on the care of HNHC patients during transition (Bleich et al., 2015), care coordination and case management remain the primary strategy of the studies included in this review. The review found the following themes: successful interventions featured models that target specific population segments; current interventions rely on high investment in labor with low technology integration or optimization; interventions focus on a single organization, system, or type of care; and structured measurement of continuity is lacking.

The importance and prevalence of targeted interventions aimed to address unique population segments are clear from the studies in this review. Population segments of HNHC patients exhibit varying levels of complexity that require triage to determine appropriate intervention type and content. Although primary and comorbid conditions, utilization habits, and health insurers serve as proxies for identification of need and cost, studies in this review failed to pinpoint a clear, evidence-based, replicable method of targeting population segments for greatest impact. Unique programs with a variety of interventions, such as embedded behavioral health (Steele et al., 2017), complex care management (Boult et al., 2011), and the imPACT model (Zulman et al., 2017), proved successful, but strategies to triage populations to programs that match their complexity remain unclear. Without triaging tool or strategy, targeted interventions may not be appropriately customized for population segments in need and resources can be misapplied or misspent. For example, in a primary care practice with medically complex patients, addressing behavioral health needs within the practice may not be economically feasible, but with targeted screening, specific patients in need could be referred to an integrated behavioral health model.

Second, the studies in this review largely comprised interventions that require substantial investment in human resources, with scant investment in the optimization or use of health information technology. Few interventions were based in technology, only one (Hardin et al., 2017) referenced an HIE, and none were automated on the basis of an algorithm. Although clinical work is refined through technology and technology could be used to make the work of clinicians more efficient and measurable, the full potential of current technological offerings has not been realized in the science of care coordination. According to Popejoy et al., the quantification of care coordination activities is currently dependent on care coordinators documenting their activities (Popejoy, Galambos, et al., 2015a; Popejoy, Jaddoo, et al., 2015b) and there is little, if any, technological integration to enhance efficiency of practice. Without understanding what care coordinators do, how much is done, and at what cost, care coordination as an intervention remains poorly understood in terms of how much effort is needed to produce positive patient outcomes (Popejoy, Galambos, et al., 2015a; Popejoy, Jaddoo, et al., 2015b; Popejoy, Khalilia, et al., 2015c). Further limitations to a science dependent upon personnel and lacking in automation are the financial contribution required to sustain care coordination teams. In addition, although the social needs of many HNHC patients require extensive human interaction, interventions are difficult to measure, track productivity, and variance can ensue. Two studies speak directly to the potential for EHR and information exchange optimization via the use of a care plan or care map for medically complex patients (Hardin et al., 2017; Ohar et al., 2018), demonstrating the potential for automation.

The third theme found in the analysis of these studies was that interventions were place-based and did not effectively cross the continuum of care, nor was technology used to increase the capacity to cross the continuum of care. Only two interventions bridged multiple settings (Watkins et al., 2012; Kitzman et al., 2017), and care coordinators were primarily focused on outcomes relevant to their organization. Cross-sector (including community-based organizations) communication and collaboration are of vital importance and extend beyond simply attending outpatient appointments or embedding behavioral health services in a primary care setting. Communication about patients consumes nearly 50% of care coordination time, followed by 22% of time spent in assessing needs and goals (Popejoy, Galambos, et al., 2015a; Popejoy, Jaddoo, et al., 2015b). Care coordinators have information that needs to be efficiently communicated across all health care sectors to manage increasing social complexity of patients. Despite ample evidence that social complexity contributes to poor outcomes, there is very little programming for managing collaboration with community-based organizations in the studies in this review. Hardin et al.'s (2017) cross-continuum tool included social service information; however, sharing was primarily contained to the providers in the hospitals of care.

Finally, this review set out to describe current care coordination models and to query whether they decreased low-value utilization and improved continuity of care. Although utilization was measured extensively, this review found that there was no systematic, structured, or even defined measurement of continuity. Utilization is likely the primary outcome measured because of availability of data found in claims data and value-based regulatory requirements. Although continuity tracking is possible through Medicare TCM billing, TCM remains underutilized and its impact unclear (Huckfeldt, Neprash, & Nuckols, 2018). The Agency for Healthcare Research and Quality (2013) Continuity of Care Practices survey is a lengthy alternative, dependent upon patient self-report. The ways to measure continuity are poorly defined and inconsistently applied and may not be a measure of actual practice. Furthermore, the question remains whether improved continuity correlates with improved patient outcomes, quality of life, or decreased burden of illness. Patient experience of care, adherence to postdischarge appointments, and outpatient utilization have the potential to serve as proxies for elements of a measure of continuity; however, few studies in this review measured these outcomes or discussed continuity as a measurable goal.

Future Research

In tandem with described themes, future research must address the growing need for a systematic identification of population segments best suited for targeted interventions, such as in the PACT/imPACT model (Zulman et al., 2017), and do so by utilizing data mining and structured algorithms for standardized patient selection. It is clear from recent complex care coordination research that interventions applied across diagnoses and social determinants have the potential to show substandard results (Finklestein, Zhou, Taubman, & Doyle, 2020). With costly care coordination resources, it is vitally important to risk stratify in a targeted manner and consider that HNHC patients require high-intensity treatment in the immediate postdischarge window. Whatever the level of care, this costly, time-intensive service must be specifically applied and the method for successfully targeting populations should be further studied.

Future research should test automated information exchange platforms and protocols using HIEs, comprehensive shared care plans (Baker et al., 2016; Dykes et al., 2014; Cipriano et al., 2013), and EHR modifications that span organizations and settings of care and touch on the importance of evidence-based decision-making and accountability. For example, clinical decision support for discharged patients with multiple chronic conditions, delivered using HIE, facilitated nurse care coordinator outreach and care planning and resulted in a significant reduction in emergency visits (Hewner et al., 2018). In addition, studies testing the improvement in team member accountability when HIE notifications are limited to the HNHC population should be pursued.

Finally, and perhaps most importantly, future studies must outline the parameters for successful achievement of continuity as an outcome. After receiving disappointing results from their recent complex care coordination RCT (Finklestein et al., 2020), Camden Coalition CEO Kathleen Noonan confirmed the need for new metrics, saying, “While the RCT used the 180-day hospital readmission rates as a proxy for improved health, systems-level interventions cannot be effectively appraised using a single quantitative metric” (Noonan, 2020). In addition to process and productivity metrics, a structured understanding of continuity and its quantitative parameters is a necessary step in diversifying the measurement of this often-varying field of care.

Limitations

This review is limited by the design of many of the studies; only three represent true RCTs. As quality assessment is not a requirement of scoping reviews, articles were not excluded on this basis; this may be a source of bias in this review. Also, limiting our selection to U.S.-based studies removes many innovative international models for this population.

Implications for Case Management Practice

It is essential that care coordination practices serve as the bridge between multiple health care settings and community-based service organizations. One way to do this is to improve the use of HIE across care settings in both integrated and unintegrated health care systems, so all providers receive health care information about the patients they serve in a timely and usable way. For care coordination to bridge multiple settings, there must be shared care plans that cross settings and providers that identify who is responsible and accountable for interventions and activities within those plans and set key short- and long-term care outcomes. It is essential that emerging current and emerging technologies that add efficiency to care management be used as current shortages in health care professional are expected to worsen in the upcoming decades. There is need for care coordinators to have access to technology to provide data that support early illness and adverse event recognition so that timely and effective interventions can be put in place before serious illness and injuries occur (Rantz et al., 2017).

Conclusion

Reflecting on the characteristics of HNHC patients, we conclude by continuing to ask the following questions: How are we to move beyond the barriers of resource-heavy interventions and begin to design HNHC care coordination in a way that is agile, measurable, structured, replicable, and standardized? How do we efficiently deploy resources where they are needed, in measured ways, using innovative health information technology, to influence diverse outcomes?

This review has demonstrated that significant gaps in research and practice remain with regard to clearly aligning the HNHC population with the most effective interventions that (a) strategically utilize health information technology to amplify existing care coordination resources, and (b) look across sectors of the continuum of care by including community-based organizations that specialize in addressing social determinants of health. In addition, the nearly complete void of a standardized measurement of continuity of care as an outcome is striking, and this profound gap should be the focus of immediate future research for this population. The importance of continuity as a measure that directly improves patient experience and lessens the burden of care is of significant interest to patients, clinicians, and scientists alike. Care coordination seems to work in a variety of settings, with different populations, requiring a wide variety of team members. The challenge remains to move beyond utilization outcomes to studies that impact patient experience of care, continuity, and overall burden of illness.

The literature continues to show that care coordination of HNHC patients is impactful in its ability to decrease low-value health care utilization in single settings of care, but this impact comes at a price. Care coordination is a labor-heavy, therefore expensive, intervention that does not have outcomes that can be readily measured upon which to judge effectiveness. With the diversification of value-based payment moving alongside the increasing acuity of an aging patient population, we must understand and begin to standardize the use of technology and data that are difficult to extract or not typically used, such as nursing notes and ancillary clinician narrative, to pinpoint appropriate patients and tailor interventions toward standardization and scalable outcomes.
